(CNN) — Justin Bieber’s blood-alcohol content was below 0.08% in two breath tests that authorities gave him relating to his arrest on suspicion of driving under the influence in Florida on Thursday, a source close to the investigation said.

The source did not give the exact level.

The 0.08% is generally the legal limit for drivers in Florida, though 0.02% is the limit for drivers under the legal drinking age of 21.

Police said Bieber admitted to drinking, using marijuana and taking prescription pills.
